First-order deviations from the theoretical standard model value for $g-2$ due to these String Theory-motivated effects are derived. A constraint of $M_f>577 GeV$ for the new fundamental scale is given.Proceedings of the Nuclear Physics Winter Meeting 2004, Bormio, ItalyHigh Energy Physics - Phenomenologytext
